If the system detects that the driver has not
steered the vehicle for a considerable period of
time or has removed their hands from the steering
wheel, display 1 appears. If the driver still does
not steer the vehicle, a warning tone sounds in
addition to the visual warning message.
If the driver does not react to the warning for a
considerable period, the system can initiate an
emergency stop (
/
page 249).
The warning is not issued or is stopped when the
driver gives confirmation to the system:
R
The driver steers the vehicle.
R
Depending on the country: the driver presses
a steering wheel button or operates Touch
Control
If Active Steering Assist detects that a system
limit has been reached, a visual warning is issued
and a warning tone sounds.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers (

page 228).
System limits
Active Steering Assist has a limited steering tor-
que for lateral guidance. In some cases, the steer-
ing intervention is not sufficient to keep the vehi-
cle in the lane or to drive through exits.
The system may be impaired or may not function
in the following instances:
R
There is poor visibility, e.g. due to snow, rain,
fog, heavy spray, greatly varying light condi-
tions or strong shadows on the carriageway.
R
There is glare, e.g. from oncoming traffic,
direct sunlight or reflections.
R
Insufficient road illumination.
R
The windscreen is dirty, misted up, damaged
or covered in the vicinity of the camera, e.g.
by a sticker.
R
No, or several, unclear lane markings are pres-
ent for one lane, or the markings change
quickly, forexample, in a construction area or
junctions.
R
The lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow.
R
If the distance to the vehicle in front is too
short and thus the lane markings cannot be
detected.
R
The road is narrow and winding.
R
There are obstacles on the lane or projecting
out into the lane, suchas object markers.
The system does not provide assistance in the fol-
lowing conditions:
R
On tight bends and when turning.
R
When crossing junctions.
R
At roundabouts or toll stations.
R
When towing a trailer.
R
